I see the problem, you are using g77 ( a Fortran 77 compiler) and not gfortran.LAPACK now includes some f90 features and you must use a f90 compiler.If you replace g77 by gfortran in your make.inc, that should work.Julie

I'm in a situation where I have to use g77. I'm using legacy code for a scientific application that doesn't compile properly with gfortran. Is there an older version of LAPACK without the Fortran 90 components I can use?
